Drill out the existing foam in the 3″ long blade stub inside the shaft.

Use a heat gun to heat the outside area of the blade stub sleeve left inside the shaft, it will have to be hot. Be patient, it may take a minute.

Using needle nose pliers (regular pliers will also work) grab the 3/4″ piece that extends past the shaft, try to carefully work the carbon sleeve loose. If it does not break loose reheat and try again. The shaft is hot
and rubbery be careful not to damage it!

Once the blade stub sleeve breaks loose from the shaft pull it out.

Clean out the old epoxy glue that may be left in the shaft, sanding works well. Empty debris from inside the shaft.

Apply epoxy glue to the new ZRE Blade stub and insert it inside the shaft, the larger ZRE sticker should face forward

Line up grip to the end of blade and clean excess glue and let dry before using.
